[0019] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a laboratory purification workbench capable of removing suspended particulate matter includes a clean workbench 1. A frame 2 is fixedly installed at the inner end of the clean workbench 1. The frame 2 is of a hollow structure, and a support plate 3 is rotatably installed inside the frame 2. A rotating mechanism for driving the support plate 3 to rotate is installed outside the clean workbench 1. A cleaning mechanism extending below the clean workbench 1 is installed at the back end of the frame 2; the rotating mechanism is used to drive the upper end surface of the support plate 3 to rotate downward or drive the lower end surface of the support plate 3 to rotate upward; the cleaning mechanism is used to clean the lower end surface of the support plate 3.

[0020] In this embodiment: when using the device, after starting the purification device inside the device, the purified air body blows downward from above the clean workbench 1, squeezing out the original air. At the same time, start the rotating mechanism. The rotating mechanism drives the support plate 3 to rotate 180 degrees, so that the originally upward-facing surface of the support plate 3 rotates downward, and the originally downward-facing surface rotates upward, realizing the surface replacement of the support plate 3. And synchronously start the cleaning mechanism. The running cleaning mechanism cleans the downward-facing surface of the support plate 3, facilitating the next use, thereby forming a better cleaning effect and cleaning the dust attached to the surface of the support plate 3.

[0021] Please pay special attention to refer to Figure 1 and Figure 2 , the rotating mechanism includes a worm 6 rotatably connected between two fixed frames. The fixed frames are fixedly connected to the side surface of the clean workbench 1. A rotating motor 5 is installed outside one of the fixed frames. The output end of the rotating motor 5 penetrates the fixed frame and is rotatably connected to the center of one end of the worm 6 through a coupling. A worm gear 7 is meshed with the outer circumference of the worm 6. A rotating shaft rotatably connected to the clean workbench 1 is connected to the center of one side of the worm gear 7. The rotating shaft penetrates the support plate 3 and is fixedly connected to the support plate 3.

At the same time, since the rotating mechanism is composed of the worm wheel 7 and the worm 6, it has a one-way transmission characteristic, so the support plate 3 can remain stable when subjected to force;

[0023] It should be noted that the rotation degree of the rotary motor 5 is controlled by the controller, so that the support plate 3 can rotate 180 degrees in a single drive.

[0025] In this embodiment: after the support plate 3 rotates one hundred and eighty degrees, and before the bottom end surface of the support plate 3 rotates upward, the forward and reverse motor 8 is started, and the forward and reverse motor 8 drives the screw 9 connected thereto to rotate. At this time, the connecting shaft 10 threadedly connected to the screw 9 moves under the action of its internal thread, and the other connecting shaft 10 is forced to slide along the outer wall of the guide rod 12, and the two connecting shafts 10 drive the rotating shaft 14 to move accordingly. During the movement of the rotating shaft 14, the gear 15 is driven to engage with the rack 4. At this time, the gear 15 rotates during the movement, and the gear 15 drives the rotating shaft 14 and the cleaning roller 11 to rotate. The rotating cleaning roller 11 drives the cleaning felt to clean the bottom surface of the support plate 3, and wipes off the dust attached to the support plate 3.

[0026] Please refer to Figure 4 The outer wall of the cleaning roller 11 is sleeved with a cleaning felt, and the head and tail ends of the cleaning felt are connected by Velcro.

[0027] In this embodiment: after the cleaning felt is used, it can be removed from the cleaning roller 11 by separating its head and tail;
